“Happy 85th to my constantly classily clad Abadaba,” she wrote as the caption for an Instagram photo featuring Reynolds wearing all green as Carrie Fisher stands behind her.

Both Reynolds and Lourd’s mother, Fisher, passed away suddenly this winter just one day apart from each other. Last week, Lourd’s uncle, Todd Fisher, gave an update on how the young actress was dealing with the losses.

“There’s a vacuum in the room, and she’s feeling it, and we’re all feeling it,” he said. “I’m letting [Billie] breathe, you know? She needs to breathe. She needs to step back from all of this loss.”
